My pump won’t stay on my valve extenders because it does not have the threading required for it to grip or stay on the valve. Is there any solution to this? Perhaps some sort of adapter?

I’ve never seen a valve or vale extender with a smooth bore. The closest I’ve seen are Zipp Tangente extenders, but even these have a knurl in place of the thread. I think you’ll have to get different extenders with a thread at the tip, like these.
I have never had much luck with extenders in the past. I only run 80mm tubes on my 60mm rims. You can buy tubes online in bulk for far cheaper than in most shops. I generally buy 10-12 at a time and they cost $4-$6 each even for 80’s
